Did you get a notice from Hyundai, and are they extending any warranties based on this TSB?
I would ask the dealer what specific prep work they do. Reading the tsb I didn’t see any specific rust removal prep work.
These are always difficult. In theory, cutting off the oxygen and moisture from the rusty area should stop the rust, but they need to be perfect to accomplish this.
Good luck, let us know how it goes.
